Audley Harrison says that British heavyweight champion Scott Gammer is a "joker" who cheapens the belt.

But Gammer, who turned down a potential February bout with the Olympic champion, says he will be looking for Harrison after facing Danny Williams.

"Gammer has devalued the British title by not fighting the best available challenger," Harrison told his website.

"He spent a year calling me out and as soon as he sees me put in a good fight he runs away from the challenge."

Harrison faces European champion Michael Sprott on 17 February, while Gammer meets Danny Williams - stopped by Harrison in three rounds in December - at the Cwrt Herbert Sport Centre in Neath on 2 March.
